This investigation seeks to investigate the relationship of kinematic fluid viscosity to the effective power transduction seen by a hydraulic motor. Applications of this research specifically relate to energy recovery from a vehicle suspension system through the shock absorbers. A regenerative, hydraulic-based, rotary shock absorber was designed and fabricated for the purposes of this investigation. The kinematic viscosities ranging from 100 cSt to 200 cSt were used in the fluid circuit and tested for maximal efficiency of the hydraulic system. Balance between shear-force losses in the fluid circuit, and effective transfer of momentum at the water-wheel type hydraulic motor demonstrates that optimized performance of the system is attained when a midpoint is reached in the kinematic viscosity of the fluid.
